Abstract

Asterocheres flustrae n. sp. is described from Flustra foliacea L. (Bryozoa) found in the Kandalaksha Bay of the White Sea. This is the first siphonostomatoid copepod to be reported in association with a bryozoan. Distinctive features of the new species are: (1) a female with 21- and male with 18-segmented antennules; (2) five setae on the inner lobe of the maxillule with one much reduced; (3) an aesthetasc on the syncoxa of the maxilla; (4) a 6-segmented maxilliped with a distal claw; and (5) the armature of endopodal segments 2, 1, 1 and 1. Sexual dimorphism was observed not only on the antennules, but also for maxilliped and legs 1–6. By using SEM some new fine structures were revealed, including: one seta on each of antennulary segments 1 to 4, 6 and 8 with a nipple-like tip and an apical pore surrounded at its base by a circlet of cuticular denticles; a rostral region having a circular area ornamented with minute cuticular protuberances; and the labrum ornamented with fine hair-like setules on either side of its apex.
